I have a greatly varied sleep schedule as I have a project oriented job so no one cares when I work or for how long as long as I get everything done by the deadline, so on average I'll just rush to get it done as soon as I can sleeping 4 hours a night and then after that hellish week, ill sleep for about 12 hours straight and then on to the next

Wow. This poll brings back a lot of memories. I remember when I was 15, I would stay up all night to the next day watching at least 25 episodes non-stop (if not more). I used to be really depressed back then so watching anime usually heightened up my spirit a bit (even though my parents scolded at me for it) . So at that time, I would estimate getting a minimum of 3-4 hours of sleep. Sometimes I barely slept an entire day just to watch anime shows. And I would skip school also cause I hated it so much.
